In this directory, we'll put a JSON file for each extension we want to deploy. JSON (suffix .json) is a data interchange format, kind of like XML.

Put JSON files in the directory

First, go to the extensions store and chose the extension you want. On the address bar, you will find the extension ID at the end, that you need. eg. https://chrome.google.com/webstore/detail/esna-ilink-for-webex/jdioafpkpgfnbnlikaocffanjeajajob -> Extension ID is "jdioafpkpgfnbnlikaocffanjeajajob"

Create a file in called /Library/Application\ Support/Google/Chrome/External\ Extensions with the Extension_ID.json (e.g. /Library/Application\ Support/Google/Chrome/External\ Extensions/jdioafpkpgfnbnlikaocffanjeajajob.json)
